iOS 自定义步骤进度条

新项目要做入驻功能,其中包括一个入住流程,类似登录或者注册流程如下图。

iOS 自定义步骤进度条

之前想着用自己绘图来做,可是又懒不想多写代码，所以就想着能不能用进度条来做。

1.用进度条做的首先要解决的是进度条的高度问题,可以通过仿射变换来扩大高度。

 progressView.transform = CGAffineTransformMakeScale(1.0f,2.0f);

2.用进度条要设置进度progress要与按钮对应

通过步骤的索引来改变进度的值和按钮的图片。由于按钮的左右有间隔所以要注意-1、0和最后一个的progress值。

3.扩展

看有一些类似查公交、车站运行的APP有的可以点击站点，所以就用按钮来做，这样可以扩展。

5.使用和效果

 NSArray *arr=@[@"区宝时尚",@"区宝时尚",@"时尚",@"区宝时尚",@"时尚"];     StepProgressView *stepView=[StepProgressView progressViewFrame:CGRectMake(0, 100, self.view.bounds.size.width, 60) withTitleArray:arr];     stepView.stepIndex=2;     [self.view addSubview:stepView];
